Troubleshooting Fuel Filter System Issues (Part 2) | Preventing Clogs

Hello, everyone.

This is Enta.

This is a follow-up to the filter replacement I did the other day.

RPD130C Diesel Engine

In the previous post, I replaced the fuel filter.

Older diesel engines won't start unless you bleed the air out of them.

Next, we'll bleed the air.

While newer diesel engines may not have one, our machine is equipped with the bleed pump shown in the photo above.

Turn the pump to the left to extend the piston so it can move.

Injection Pump

Loosen the bolt mentioned above by about two turns.

Please do not remove this bolt.

That's because there are small springs and balls inside this bolt, so,If you drop it on site, it's game over.That's it.

There's no doubt that finding one on site would be an incredibly difficult feat, lol.

 

Once you loosen this bolt, the bleed pump will start moving the piston.

When you pump it, the diesel fuel comes out with a squelching sound.

It looks something like this.

If this allows the diesel fuel to flow smoothly without any air, the bleeding process is complete.

Tighten the bolt you loosened earlier securely, and check that the fuel filter is tight.

Please check everything. (If possible,Pointing and Naming Is the Best!

Please wipe up any spilled diesel fuel or place an absorbent mat underneath beforehand.

 

We have completed the process from replacing the fuel filter to bleeding the system.

If it still doesn't work, there's another cause.

 

See you later.
